Modi renames 3 islands of Andaman and Nicobar

Washington, Apr 23: Air pollution over northern India has plummeted to a 20-year-low for this time of the year, according to satellite data published by US space agency National Aeronautics and Space Administration (NASA).
The US space agency's satellite sensors observed aerosol levels at a 20-year low post the countrywide lockdown, implemented to slow the spread of the novel coronavirus.

"We knew we would see changes in atmospheric composition in many places during the lockdown," said Pawan Gupta, a Universities Space Research Association (USRA) scientist at NASA''s Marshall Space Flight Center. "But I have never seen aerosol values so low in the Indo-Gangetic Plain at this time of year," added Mr Gupta.

Acting Assistant Secretary of State for South and Central Asia Alice G Wells tweeted, "These images from NASA were taken each spring starting in 2016 and show a 20-year low in airborne particle levels over India. When India and the world are ready to work and travel again, let's not forget that collaborative action can result in cleaner air."

The data published with maps show aerosol optical depth (AOD) in 2020 compared to the average for 2016-2019. Aerosol optical depth is a measure of how light is absorbed or reflected by airborne particles as it travels through the atmosphere.

If aerosols are concentrated near the surface, an optical depth of 1 or above indicates very hazy conditions. An optical depth, or thickness, of less than 0.1 over the entire atmospheric vertical column is considered "clean." The data were retrieved by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra satellite.

In the first few days of the lockdown, it was difficult to observe a change in the pollution signature. "We saw an aerosol decrease in the first week of the shutdown, but that was due to a combination of rain and the lockdown," said Mr Gupta.

Around March 27, heavy rain poured over vast areas of northern India and helped clear the air of aerosols. Aerosol concentrations usually increase again after such heavy precipitation.

"After the rainfall, I was really impressed that aerosol levels did not go up and return to normal. We saw a gradual decrease and things have been staying at the level we might expect without anthropogenic emissions," Mr Gupta said.

On March 25, the Indian government placed its 1.3 billion citizens under a strict lockdown to reduce the spread of COVID-19. The countrywide mandate decreased activity at factories and severely reduced car, bus, truck and airplane traffic. Every year, aerosols from anthropogenic (human-made) sources contribute to unhealthy levels of air pollution in many Indian cities.

Aerosols are tiny solid and liquid particles suspended in the air that reduce visibility and can damage the human lungs and heart.

In southern India though, the story is a little hazier. Satellite data show aerosol levels have not yet decreased to the same extent. In fact, levels seem to be slightly higher than in the past four years. The reasons are unclear but could be related to recent weather patterns, agricultural fires, winds or other factors.

"This a model scientific experiment," Robert Levy, program leader for NASA's MODIS aerosol products, said about the lockdown and its effects on pollution.

"We have a unique opportunity to learn how the atmosphere reacts to sharp and sudden reductions in emissions from certain sectors. This can help us separate how natural and human sources of aerosols affect the atmosphere," Mr Levy added.

Lucknow, Jun 20: A media body on Saturday described as "an act of intimidation" the filing of an FIR in Uttar Pradesh against a journalist over a report on the impact of the lockdown on a village, saying it was part of an "established pattern" of harassment of independent scribes.

In a statement, the Media Foundation put on record its strong protest over the FIR filed by the Uttar Pradesh government against Supriya Sharma, executive editor of news portal Scroll.in.

The case was filed against Sharma for allegedly misrepresenting facts in a report on the impact of the lockdown in a village adopted by Prime Minister Narendra Modi, police sources had said on Thursday.

The FIR against Sharma and the Scroll editor-in-chief is an "an act of intimidation and a case of abuse of process", intended to discourage honest and critical reporting, the Media Foundation said.

The Media Foundation was started in 1979 with the aim of upholding freedom of speech, expression and information.

The FIR against Sharma is only the latest instance of similar coercive actions against professional journalists, part of "an established pattern of harassment and humiliation of independent journalists", it said,

"It is an unacceptable encroachment on press freedom," said the foundation, whose chairperson is veteran journalist Harish Khare.

The Media Foundation called upon the judiciary, and central and state governments to uphold the spirit of freedom of speech and expression as guaranteed in the Constitution.

New Delhi, Jun 18: Prime Minister Narendra Modi on Thursday said he is "deeply grateful" for the overwhelming support shown by the global community for India''s membership of the UN Security Council.

India will work with all member countries to promote global peace, security, resilience and equity, he said.

India garnered 184 votes out of the 192 ballots cast in the General Assembly to win the election for the non-permanent seat in the powerful Security Council.

India''s two year term will begin on January 1, 2021.

This is the eighth time that India will sit at the UN high-table, which comprises five permanent members and 10 non-permanent members.

"Deeply grateful for the overwhelming support shown by the global community for India''s membership of the UN Security Council," the prime minister wrote on Twitter.

India will work with all member countries to promote global peace, security, resilience and equity, he said.
